Bubble

A bubble level. Hold any of the phone's four sides against an object to test it for plumb/level, or lay it down on a flat surface for a 360° level.

Features: - Calibrate each side of the phone independently. - Show the numeric angle. - Speak the angle out loud. - Flash the light, beep, or buzz when level. - Show the angle as pitch. - Tap screen to lock angle.

Working good on my S3 Like how you can calibrate for each side of the phone, so you can still use if your case or phone is not flat or uniform on every side. Wouldn't trust it for anything important, but it's always with me and I believe it gives me a pretty good idea if something is level or not.

Oh... After reading all the comments, I thought this was going to be a nice app. I was wrong! Seriously, I had this on my tablet for exactly 43 seconds, and was certain it was rubbish. Uninstalling. :(
